Hi Darshan Singh,
Machines can be better but with time but never best. Humans will always have command over the machines and in the field of Medicine, they can only assist the doctor but never repalce them.
Mschines are used in medical profession for the benefit of patients only. They involve minimal invasion and can be operted easily. Although machine can be used in process but the process can never be decided by machines,
Hope this might helps you.
All the best.
